The substance is a mix of water and cornstarch. This property defined that something can be solid and liquid at the same time. The mixture is two parts cornstarch to one part water. It demonstrates the properties of non-Newtonian fluids. Non-Newtonian fluids are solid if you apply a sudden force and liquid if you apply a steady, slow force.
In the mix, there are tiny cornstarch particles evenly distributed. When a steady slow force is applied, the particles have time to move out of the way. So the object slides through, as it would in a liquid. When a sudden force is applied, the particles don’t have time to move out of the way. So the object is stopped, as it would be on solid surface.
Viscosity is the rate at which fluid flows. Common fluids, like water, have a consistent viscosity, so they flow the same regardless of what force you apply. In Non-Newtonian fluids, viscosity can change. Apply a sudden force, and the viscosity rapidly increases, forming a semisolid surface. You can jump, bike and even flip in this fluidic pool or water area. It is important to keep applying high force on whatever you do with this fluidic water.
